The first time I drove Idaho's Magruder Corridor I brought a chainsaw. This is a long, lonely route, with NO workarounds or detours. The Forest Service warns travellers of the possibility/likelihood of trees across the road.
BUT...a chainsaw is a single-purpose tool, takes up a lot of room, is expensive, requires gas & oil, requires frequent maintenance, requires significant safety apparel, and is subject to failure for a variety of reasons.
The humble axe is a multi-purpose tool, takes up little room, is inexpensive, requires no consumables and very little maintenance, and is ultra reliable.
On subsequent trips I've left the chainsaw at home in favor of the axe. Yes, it's more work to clear the trail, but this task is very seldom necessary. Heck, even with the chainsaw I'd still want an axe or at least a hatchet for chopping kindling and splitting firewood.
